deletebutme

Delete everything except for specific files (in this case, please keep index_a.js and index_a.css).

Of course, you can also use --inverse 1 to only remove them instead.

npm install deletebutme -g

~$ deletebutme delete --deleteDir /path_to_the_deletion_folder  --filterFileDir /path_to_the_items_need_to_stay.txt
